Description
Die Erfindung betrifft ein Verfahren zur Behandlung von insbesondere entzündlichern Krankheitszuständen in der Mundhöhle durch Einbringen einer von einer Lichtquelle aktivierbaren Substanz.The The invention relates to a method for the treatment of in particular entzündlichern disease states in the oral cavity by introducing a substance which can be activated by a light source.
Stand der Technikwas standing of the technique
Unter Photodynamische Therapie wird ein photochemisches Verfahren verstanden, das bisher vor allem in der Krebstherapie Anwendung fand. Unter diesem Begriff wird allgemein eine lichtinduzierte Inaktivierung von Zellen, Mikroorganismen oder Molekülen verstanden. Ein Wirkstoff heftet sich an die zu bekämpfenden Zellen an und wird dann durch Licht aktiviert Eine Modifikation dieses Prinzip findet in der Bekämpfung von Mikroorganismen Anwendung – die „Antimikrobielle Photodynamische Therapie" (APT). Dabei ist das Ziel nicht die Vernichtung körpereigener (Tumor) – Zellen, sondern die gezielte Bekämpfung lokaler Infektionen, die Bekämpfung von Mikroorganismen. Das Wirkungsprinzip der APT beruht auf der selektiven Anfärbung der Mikroorganismen durch einen sogenannten Photosensitizer und der Zerstörung der Keime durch Belichtung mit einer geeigneten, auf den Photosensitizer abgestimmten Lichtquelle.Under Photodynamic therapy is understood as a photochemical process which has been used mainly in cancer therapy. Under This term is generally a light-induced inactivation understood by cells, microorganisms or molecules. An active ingredient attaches itself to the to be combated Cells and then is activated by light A modification This principle takes place in combat of microorganisms application - the "antimicrobial Photodynamic Therapy "(APT) the goal is not the destruction of the body's own (tumor) cells, but the targeted fight local Infections fighting of microorganisms. The mode of action of APT is based on the selective staining of the microorganisms by a so-called photosensitizer and of destruction the germs by exposure with a suitable, on the photosensitizer matched light source.
Ein entsprechendes Verfahren ist aus der WO 01/87416 A1 bekannt. Mit Hilfe der lichtaktivierbaren Substanz, insbesondere eines Farbstoffes, werden die Mikroorganismen, sensibilisiert und/oder angefärbt und nach Bestrahlung mit Licht geeigneter Wellenlänge und Energiedichte abgetötet: Die mittels eines Bestrahlungsgeräts, insbesondere eines Lasergeräts, erzeugte Energie wird damit auf die Mikroorganismen konzentriert und die Gleichgewichtslage von Reaktionen, welche auch im nicht belichteten Zustand im „normalen" Milieu ablaufen, werden verschoben und in der Folge werden die Mikroorganismen zerstört.One corresponding method is known from WO 01/87416 A1. With Help the light-activatable substance, in particular a dye, are the microorganisms, sensitized and / or stained and After irradiation with light of suitable wavelength and energy density killed: The by means of an irradiation device, in particular a laser device, generated energy is thus concentrated on the microorganisms and the equilibrium position of reactions, which also in not expire exposed state in the "normal" milieu, are moved and as a result, the microorganisms are destroyed.

Aufgabetask
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren der o.g. Art zu entwickeln, bei dem ein geeigneter Wirkstoff Anwendung findet, der vor allem auch nach kurzer Zeit nicht mehr nachweisbar ist.task The present invention is to provide a method of the above-mentioned. Kind too in which a suitable active substance is used, the especially after a short time is no longer detectable.
Lösung der AufgabeSolution of task
Zur Lösung der Aufgabe führt, dass die Substanz den Wirkstoff Indocyaningrün enthält und das Spektrum der Lichtquelle nennenswerte Anteile im Bereich von 700–1.000 nm emittiert.to solution the task leads that the substance contains the active ingredient indocyanine green and the spectrum of the light source significant proportions in the range of 700-1,000 nm emitted.
Indocyaningrün ist ein Infrarotfarbstoff, der in der medizinischen Diagnostik verwendet und unter dem Namen IR 125 als Laserfarbstoff eingesetzt wird. Es findet als intravenöses Diagnostikum mit einem breiten Spektrum in der Herz-Kreislauf-, Mikrozirkulations- und Leberfunktionsdiagnostik Anwendung und vor allem auch bei der Messung im Auge bzw. der Netzhaut.Indocyanine green is a Infrared dye used in medical diagnostics and is used under the name IR 125 as a laser dye. It takes place as intravenous Diagnostic with a broad spectrum in the cardiovascular, microcirculation and liver function diagnostics application and especially in the case of Measurement in the eye or the retina.
Gemäss der vorliegenden Erfindung wird nun ein völlig neues Anwendungsgebiet eröffnet, welches nicht zu erwarten war, nämlich die Verwendung zur Behandlung von insbesondere entzündlichen Krankheitszuständen in der Mundhöhle im Zusammenwirken mit einer aktivierenden Lichtquelle. Die Substanz hat den grossen Vorteil, dass sie nach ca. drei Stunden nicht mehr nachweisbar ist.According to the present Invention now becomes a completely new application area opened, which was not to be expected, namely the use for the treatment of in particular inflammatory disease states in the oral cavity in cooperation with an activating light source. The substance has the great advantage that it will not work after about three hours is detectable.
Als Lichtquelle sollen vor allem Halbleiterlaser (Diodenlaser) oder Licht emittierende Dioden (LED's) eingesetzt werden. Die eingesetzten Lichtquellen sollen bevorzugt Licht mit einer Wellenlänge im Bereich zwischen 780–830 nm emittiert. Die Ausgangsleistung der Lichtquelle liegt bevorzugt im Bereich zwischen 50 mW und 5.000 mW. Dies ergibt eine Bestrahlungsdosis zwischen 0,5 J–50 J bei einer Belichtungsdauer von 10s–100s.When Light source should be mainly semiconductor laser (diode laser) or Light emitting diodes (LEDs) be used. The light sources used should be preferred Light with a wavelength in the Range between 780-830 nm emitted. The output power of the light source is preferred in the range between 50 mW and 5,000 mW. This gives an irradiation dose between 0.5 J-50 J at an exposure time of 10s-100s.
Bei der Applikation des Lichtes soll die Lichtquelle im Bereich zwischen 1.000 – 50.000 Hz, bevorzugt im Bereich zwischen 10.000 Hz – 20.000 Hz, gepulst werden. Dabei kann die Pause zwischen zwei Pulsen länger ist als die Pulszeit sein.at The application of the light should be the light source in the area between 1,000 - 50,000 Hz, preferably in the range between 10,000 Hz - 20,000 Hz, to be pulsed. The pause between two pulses may be longer than the pulse time.
Die Substanz wird in steriler Darreichungsform appliziert. Ferner können der Substanz weitere Inhaltsstoffe hinzugefügt werden, die entzündliche Prozesse positiv beeinflussen.The Substance is administered in sterile dosage form. Furthermore, the Substance other ingredients are added to the inflammatory processes influence positively.
Als Darreichungsform bietet es sich an, dass die Substanz in Form einer Mundspüllösung eine gewisse Zeit in der Mundhöhle verbleibt und die Belichtung des Wirkstoffs mit einer Lichtquelle nach dem Ausspülen des Wirkstoffs erfolgt. Dabei erfolgt die Belichtung des Wirkstoffs über eine Vorrichtung, welche die Lichtquelle enthält und temporär (z.B. während einer Arbeitspause oder über Nacht) getragen wird. Eine weitere Möglichkeit ist das Einbringen der Wirkstofflösung über eine entsprechende Applikationsvorrichtung, wie z.B. eine Spritze in schwer zugängliche Bereiche, wie Parodontaltaschen o.ä..When Dosage form, it suggests that the substance in the form of a Mouthwash one certain time in the oral cavity remains and the exposure of the drug with a light source after rinsing the active ingredient takes place. The exposure of the active ingredient takes place via a Device containing the light source and temporarily (e.g. while a break or over Night). Another possibility is the introduction the drug solution over a corresponding application device, e.g. a syringe in hard to reach Areas such as periodontal pockets or similar
